We are working with the OTG243 from Transdimension on an XScale (ARM) based platform. This chip is used also in the CerfComm extension board of the CerfBoard 255 from Intrinsyc. We are using the LINUX drivers provided by Intrinsyc, which seems the same Transdimension sells.

We have problems with the isochrone transfert. When using a USB camera (OV511 or OV519) we get a -18 error which seems to correspond to lost frames. Sometimes (after many errors) we can get a full image on OV511 based cameras, not on the OV519.

Does somebody has already found or solved this problem?

Francesco
